摘要
Abstract Traumatic brain injury (TBI) is a leading cause of death and disability worldwide. Long‐term changes in the microenvironment of the brain contribute to the degeneration of neurological function following TBI. However, current research focuses primarily on short‐term modulation during the early phases of TBI, not on the critical significance of long‐term homeostasis in the brain microenvironment. Notably, dysfunction of the glymphatic‐lymphatic system results in the accumulation of danger/damage‐associated molecular patterns (DAMPs) in the brain, which is regarded as the leading cause of long‐term microenvironmental disturbances following TBI. Here, a nanostructure, Nano‐plumber, that co‐encapsulates the microenvironment regulator pro‐DHA and the lymphatic‐specific growth factor VEGF‐C is developed, allowing for a sustainable and orderly regulation of the microenvironment to promote long‐term neurological recovery. Nano‐plumber reverses the injury microenvironment by suppressing microglia and astrocytes activation and maintaining reduced activation via enhanced glymphatic‐lymphatic drainage, and significantly improves the neurological function of rodents with TBI. This study demonstrates that glymphatic‐lymphatic system reconstruction is essential for enhancing long‐term prognosis following TBI, and that the Nano‐plumber developed here may serve as a clinically translatable treatment option for TBI.
